Chytridium olla A. Braun [Chytridiales, Chytridiceae sensu Vélez et al.] MycoBank no.: 153717. Mycologia 103: 118–130. 2011. Velez et al (2011) designated figures in Braun’s 1855 publication as lectotype, stating that the type no longer existed. F.K. Sparrow , however, had earlier located and photographed the species from a packet labeled “Chytridium olla A. Br. Oedogonium Landsboroughii, Freiburg in B. legit. A. Braun” in the Institute de Botanique at Strasbourg. See: F.K. Sparrow “The type of Chytridium olla A. Braun”. Taxon 22: 583–586. 1973. I believe that the Velez et al. lectotype should, instead, be considered an epitype.
